iPhone 3G Teardown 


iPhone 3G Teardown 

step 1 - 

• We performed this disassembly immediately following 
the iPhone launch at 12:01 July 11.2008. New Zealand 
time. That's 5:01 AM, July 10, Pacific time for those of 
us who aren't islanders. 

• Bookmark this page to catch all the action! We'll still be 
updating this page over the next several days as we 
learn more about the internals. 

• If you're press interested in interviewing us, we'd be 
happy to talk to you. You can reach our press contact 
at kyle at 

Step 2 

• Auckland, here we come!

step 3 

• We've arrived! 

• Five people waited in line overnight. We're in the #4 

• It's cold! 

• Vodafone are being very accommodating, and iPhone 
Jonny even brought out an exercycle!

Step 4 

• At about 5pnn, someone brought us a TV so we can 
watch us on the news. 

• At Spin, the line was 15 people, but it ballooned rapidly 
and wrapped around the corner. 


• We handed out t-shirts at the Vodafone store last night, 
and they were hugely popular. You'll have to hit eBay if 
you want one. 

• Engadget are the only other Americans who flew out, 
and they have mugshots up of the first ten people in 

Step 6 

• Our stylish shirts in action! 

• It's the middle of winter here, and just started raining. 
Fortunately, we have an awning over our heads.

• Only 135 minutes to go and about 90 people in line. 

• You can barely see the Vodafone logo from the end of 
the line. 

• Vodafone's red beanies are a big hit. 


I As you can see from the box, we got the black one. Rumor has it 
the white iPhones are out there, but as rare as an albino whale. 
This iPhone cost us $979 NZ without a contract (but locked to 
Vodafone, of course). Not sure what we're going to do with a 
Vodafone-locked iPhone in California, but we'll figure something out 

) The packaging looks familiar... 

I All right, here's the specs we know up-front: 

• The iPhone 3G is 4.5x2.4x0.48" (0.02" thicker than the 
original iPhone), and weighs 4.7 ounces (0.1 ounce less). 
For reference, this is approximately the weight of two 
unladen swallows. 

• With its new rounded back, the new iPhone feels smaller. 
Calculating the phone's volume won't be easy 
mathematically, and measuring the phone's displacement 
the easy way probably isn't a good idea. 

The display is 3.5" diagonal, 480x320 resolution for 163ppi. 
Also known as identical to the iPhone (not that we're 

Step 9 

• No surprises inside the box: 

• USB docking cable 
Standard iPhone headphones 
USB power adapter 

• Oh, what's this? A New Zealand power plug! 
We've never gotten one of these in a box before!

Step 10 

• Removing the SIM card. Fortunately for the world's 
paper clips, the iPhone 3G comes with a SIM eject tool. 

• Perhaps the least-touted new feature of the 
iPhone 3G is the flush headphone jack, 
allowing non-Apple headphones to be used 
without an adapter. Yay! 


Step 11 

• For comparison, here's a link to last-year's iPhone 
disassembly . 

• Our predictions: 

® Apple-labeled Samsung processor, [correct] 

Either some kind of GPS chip, or none at all. If 
there isn't a GPS chip, then it could be built into 
the processor. [Turns out it's an Infineon ctiip] 

Lots of chips with only Apple markings on them. 
Sometimes we can tell what they are, but most of 
the time you have to take the chip itself apart first. 

[correct, but ttiis one's clieating] 

• Removing the display!

step 12 

• Rotating the display up. 

• Apple used orange stickers to number the connectors 
to the logic board 1 through 6. 

• The camera is located in the upper right corner of the 
phone. Unfortunately, it connects to the bottom of the 
logic board, meaning you'll likely need to remove the 
logic board from the phone to remove the camera. We 
haven't tried removing the camera, but would assume 
that like the original phone, the camera can be removed 
for those wanting to bring their iPhone 3G into secure 

• A little birdy has told me that TechOnline will 
be decapping the chips we can't identify 
tomorrow, after the US release. They soak 
the chip in an acid bath to eat away the 
ceramic coating, then use x-rays and other 
fancy equipment to examine it.

Step 13 

• The display assembly separated from the unit. 

• In a significant departure from the first iPhone, it 
appears that the LCD and glass covering are separate 
components-- just like the iPod Touch. They were glued 
together before, making replacement screens very 
expensive. The glass breaks more than anything else, 
so this is great news for repairing the iPhone 3G! 

Step 14 

• We had to remove 6 Phillips #00 screws to separate 
the glass from the LCD. 

» The glass (with integrated touch sensors and chips) is 
underneath, while the LCD is being removed. 

» In the previous iPhone, the display was 
fairly monolithic. A number of components 
were connected together via the display 
assembly- now the display just connects to 
the main board. Hopefully this will make 
obtaining replacement parts easier- we've 
had trouble getting quality supplies of 
iPhone displays to sell. 


Step 15 

• Behold, the iPhone! Can you see the 3G bits inside? 

• The two boards (logic and communications) are now 
one. Rather than stacking them, as in the last model, 
they laid it out along the entire length. We're guessing 
this allowed them to make the battery longer. 

• We're not used to taking photos outside our studio, but 
these pictures are turning out great because of our 
awesome friends in NZ. 

• Props to Andrei Smirnov of Mac Solutions for helping 
us out. They are a Macintosh sales and support 
company established in 1998 and based on the North 
Shore, Auckland. Do us a favor and use his services 
the next time you're in Auckland!

Step 16 

• Uhoh. 

• Let's try removing that. 

• And the iPhone explodes! 


Step 17 

• Just kidding. Lool<, the battery isn't soldered on! 

• Apple actually listens to us! Or something. 

Step 18 

• Dock and headphone connector. 

• The primary antenna is on the other side of this part. 

• Once we get the phone completely apart, we'll start 
posting chip numbers. We'd love help identifying chips 
from all of you, send us any inside information to We'll keep it anonymous.

Step 19 

• This is where we get excited! We've done our best to 
identify everything that's on the iPhone board. 

• Semiconductor Insights and TechOnline have released 
the almost-authoritative list of all substantial iPhone 
chips. They've graciously provided us with their images. 
We're going through and verifying their results now, but 
we expect that their accuracy will surpass our own. 

• So by our count, here's the chip counts by 
manufacturer (more important chips are bold): 

• Broadcom 1, Infineon 4, Intel 1, Linear 
Technology 1 , Marvell 1 , National Semi 1 , NXP 1 , 
Samsung 1 , Skyworks 1 , SST 1 , ST Micro 1 , 
Toshiba 1 , Triquint 3 (big win!), Wolfson 1 . 

• Our list undoubtably omits a number of 
components. Don't freak out if the chip 
you spent years slaving over isn't 
mentioned, please! We're happy to 
update it if you let us know. 



.=» E-... 1* 



Step 20 

• And Marvell for the win on the CSR BlueCore Bluetooth 
+ WiFi. This is the same chip as the iPod Touch and 
first iPhone. 

• Toshiba manufactured the flash in both iPhone logic 
boards we've seen so far. We'll see if this trend holds.

Step 21 

• Intel NOR flash in the middle left of the shot: 3050M0Y0CE 

The largest chip in the top left comer is an Infineon 337S3394 
WEDGE baseband marked SP836175 G0822. 

Small chip to the right of the NOR: Infineon BGA736 (Tri-Band 
HSDPA LNA). Just beneath that is an Infineon UMTS Transceiver 
marked 338S03532Z 60814. 

• Skyworks power amplifier SKY77340 (Power Amplifier Module 
Quad) on the top right: Octopart datasheet 

• The chip in the top middle is SMP 31 6820, Infineon SM-Power3i. 
From Infineon: the part is "optimized to support modem and data 
card applications based upon X-GOLD208 and X-GOLD 608, with 
features ranging from EDGE up to 3G and HSDPA." 

« Chips we need to identify: 6475 with M logo (rumored to be Murata 
IF SAW Filter).

Step 22 

• The entire board (the EMI shield is removed from the 
right side). 

• The previous shot is the top right portion of this picture. 

• Removing the EMI shielding is tricky, so we're taking 
our time. 

• If you'd like to comment publicly, use the Gizmodo 
forums or reply via twitter to ifixit , and Summize will pull 
it up.

Step 23 

The other half of the board. Note the Apple-branded ARM on the 
left and the SIM card holder at bottom center 

» Big news: Samsung DDR SRAM markers on the processor again. 
Looks like they win on the processor front again (not that we were 
expecting anything different). 

• Processor markers: 339S0036 ARM EMC567DB 819 8900B 
N182F0A3 0825 7511.101 ZPD8163Y, 5974V CKUFBG 
HE0819 870628 P12 N3. Samsung DDR on the chip ( 
K4X1G163PC-DGC3) is slightly different from the first 
iPhone, which was K4X1G153PC. 

» SST SST25VF040B 1MB SPI Serial Flash to the left of the SIM 
card, along with a National Semiconductor LM2512AA Display 

I APPLE 338S0506 is a Wolfson WM6180C (We haven't seen 
Wolfson disguise their chips like this before). APPLE 338S0512 is 
an obfuscated NXP power management chip. 

I The GPS chip is the grey chip in the middle-right side of the board. 
It is an Infineon PBM2525 Hammerhead II ! Rumors that it would be 
integrated into the processor have been disproved 

I The round grey chip to the right of the Apple-logo processor is the 
ST Micro LIS331 DL Accelerometer . 

Step 24 

• The back of the logic board, after pulling up the metallic 

Step 25 

• The 8GB NAND flash chip (Toshiba 
TH58NVG6D1DTG80), revealed after removing a 
soldered-down cover. This chip was covered by a 
plastic shield as well, which we've partially removed to 
see the markings beneath.

Step 26 

• The three chips along the bottom are TriQuint Tritium 
PA-duplexers : TQM616035 TQM676031 TQM666032. 
Presumably each one works on a different frequency 
band: "Each highly-integrated module contains a Tx 
input filter, a linear Power Amplifier, Duplexer, and 

• This is a big win for TriQuint! Their stock 
has been doing a bit better since we 
discovered this. 


Step 27 

• The rear panel remains. Looks like that leaked shot 
was reasonably accurate. 

• Unlike the metal rear panel on the original iPhone, the 
rear panel appears to be made from ABS plastic. The 
coat on the back feels nice and is very reflective, 
hopefully it's durable as well. 

• There doesn't appear to be a serial number 
on the back panel of our phone. We don't 
know if that's unique to our phone, or true 
with all 3G iPhones. 


Step 28 

• The battery. Put your soldering irons away, they won't 
be needed! Apple part #616-0372. 

• The recycle marker on the battery is blacked out with a 
sharpie. Suspicious... 

• We were all expecting a bigger battery, and I can't 
verify this, but this page references the part number on 
the battery and lists a capacity of 11 50 mAh, not the 
1400 mAh in the original. Can anyone dig up more

Step 29 

• From top left to bottom right: Display glass, LCD, Main 
board and EMI shield. Antenna and battery. Back panel. 

• That's it! We'll keep updating the chips above, so keep 
checking back. We'll post more photos as requested, 
but we're going to snag some sleep after waiting in line 
for two nights. 

• We'd like to thank some gracious Auckland residents 
for making this happen: 

• Grant Virtue of brochuresunlimited for the facility 
in downtown Auckland. 

• Oleg Boukhvalov of Weblab for his electronics 
expertise and help with the disassembly. 

• Andrei Smirnov of MacSolutions for coordinating 

• We'll be adding a selection of iPhone 3G parts soon, as 
well as a detailed take-apart guide . 

To reassemble your device, follow these instructions in reverse order.
